Inventor: SEBASTIEN DOYON
IPC: A41F17/02
Filed: 1992-12-14
Abstract: PRÉCIS    Dans  la  pratique  du  hockey,  nous  savons  que  plusieurs utilisent le ruban adhésif (aussi appellé ruban gommé ou "tape") pour apporter une meilleure stabilité du patin au niveau de la cheville. Nous devons alors poser le ruban adhésif en serrant et en entourant bien le patin au niveau de la cheville pour assurer la stabilité recherchée. La présente invention se veut un produit de remplacement pour l'utilisation du ruban adhésif en général dans la mesure où son fonctionnement et sa conception le permettent.  Elle est formée d'une bande élastique dont on a fixé un crochet à une extrémité et une boucle,  comparable à celle d'une ceinture,  à l'autre extrémité.  Nous retrouvons également une serie de trous (comme sur une ceinture), au centre de la bande.  De tels trous permettent d'ajuster le produit selon la stabilité (ou la prise) recherchée et ceci de manière rapide de même qu'efficace.   Nous avons  seulement qu'à passer  l'extrémité  avec  le crochet  dans l'autre extrémité munie d'une boucle en serrant, puis en allant fixer, en sens contraire, le crochet dans le trou désiré.

Title: Peptide and protein fusions to thioredoxin and thioredoxin-like molecules
Inventor: MCCOY JOHN
IPC: C07K14/53
Filed: 1992-02-06
Abstract: This invention provides a fusion molecule comprising a DNA sequence encoding a thioredoxin-like protein fused to the DNA sequence encoding a selected heterologous peptide or protein. The peptide or protein may be fused to the amino terminus of the thioredoxin-like molecule, the carboxyl terminus of the thioredoxin-like molecule, or within the thioredoxin-like molecule, for example at the active-site loop of said molecule. Expression of this fusion molecule under the control of a regulatory sequence capable of directing its expression in a desired host cell, produces high levels of stable and soluble fusion protein. The fusion pro-tein, located in the bacterial cytoplasm, may be selectively released from the cell by osmotic shock or freeze/thaw procedures. It may be optionally cleaved to liberate the soluble, correctly folded heterologous protein from the thioredoxin-like portion.

Title: Electronic bell tone generator
Inventor: FALZARANO BART JR
IPC: G10H5/10
Filed: 1994-02-24
Abstract: A microprocessor provides a pulse width modulated pulse train at a predetermined frequency to a tuned resonant circuit having a transducer element. The first pulse has a predetermined width. The pulse widths of successive pulses are decreased in a predetermined manner until the pulse width reaches a minimally desired width. The next generated pulse has the first predetermined width and each successive width is decreased in the same predetermined manner. This pattern is generated repeatedly. Each one of these generated patterns produces an audible waveform from the tuned resonant circuit which changes over time. If the pulse train frequency, the pulse width modulation, and the circuit's resonant frequency are chosen correctly, the audible waveform will have the same characteristics as the waveform produced by a specified bell which has been struck.
